Patented July 19, 1932 UNITED STATES PATENT OFFICE HUGO GOLDSMITH, OF CINCINNATI, OI-IIO, ASSIGNOR TO THE P. GOLDSMITH SONS COM- PANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO CLEATED ATHLETIC SHOE AND CLEAT THEREFOR Application filed April 30,

My invention relates to cleated athletic shoes and cleats and particularly to a removable cleat construction which will enable the user of the shoe to replace the cleats when they become worn or broken.

lVhile the idea of providing a shoe with detachable cleats is not in itself new as far as I am aware, the removal of the cleats in known constructions has required the cleat to have imbedded in it some metallic shank or fastener, and it is broadly my object to provide a cleat construction in which by the simple removal or unscrewing of a nut, the cleat proper may be removed and a new cleat replaced without the necessity of providing a cleat having any fastener or metal retainer moulded within its structure.

It is further my object to provide a cleated construction in which the outwardly tapering walls of the cleat are used to retain it in position in its attachment.

The above objects and other objects to which reference will be made in the ensuing disclosure, I accomplish by that preferred combination and arrangement of parts of which I have shown several preferred modifications.

Referring to the drawing Figure 1 is a sectional View showing one type of removable cleat and attachment therefor, with a section of the shoe sole in which the attachment is secured also indicated.

Figure 2 is a sectional view in which a preferred and modified type of cleat and its attachment is shown also in combination with a portion of a shoe sole in which the attachment is fastened.

Figure 3 is a sectional view of the preferred type of lock nut construction employed with the attaching device shown in Figure 2.

Figure 4 is a side elevation of the removable cleat shown in the combination illustrated in Figure 2.

Figure 5 is a plan view of the type of attachment base which is permanently attached to the shoe sole in the combination shown in Figure 1.

Figure 6 is a plan view of the preferred type of attachment base, which is secured to 1930. Serial No. 448,762.

constructions extended clear through the sole of the shoe and required a lock nut within the shoe for holding the cleat in place.

This rendered the installation of the attachment complicated, and in case the shank wasnot set exactly proper during the moulding of the cleat, it would assume a crooked position, which was undesirable.

Referring first to the construction shown in Figure 1, I have shown an attachment base 1 having a threaded periphery 2, and with nails 3, the heads of which seat in counter.- sunk portion 4 in the upper surface of the base. The nails extend through the sole 5 and in accordance with standard practice, are bent over as indicated at-6.

I have shown a cleat 7, preferably formed of some moulded composition, which has a truncated conical shape, which seats against the upper surface of the base 1 and is held in position thereon by means of a lock nut 8 having threads 9 which engage the threads 2 of the base 1, and having an annular inwardly flaring shoulder pin which frictionally bears against the enlarged lower end of the cleat U. The tighter the nut 8 is drawn down, the tighter the cleat will beheld in position by the annular shoulder 10 of the lock nut.

In Figure 2 I have shown a preferred construction which will now be described. The base 1a has exterior threads 2a and countersunk recesses 4a with which nails 3a, which extend through the sole 5, are employed to hold the base 1a in position. The base 1a is formed with a central opening 11. The cleat 7a has a projection 12 which seats within the opening 11 in the base 1a and so tends to prevent the cleat from being tightened down by the nut 8a in other than a straight position. The lock nut 8a has an annular flaring 1 shoulder a which seats against the enlarged base of the main body of the cleat 7 a, in a substantially similar manner as in the combination shown in Figure 1.

While I have shown the attachment bases secured to the sole with nails which are bent over on the inner surface of the sole of the shoe, other means for attaching the base to the sole may be employed for holding the bases to the soles, such as screws or rivets.

While I have shown the type of cleat which is ordinarily best suited for football shoes, I by no means wish to limit myself to this particular shape of cleat. Cleats of different conformation such as are better applicable for baseball or running shoes may be employed, as it will be obvious that the principle of my invention lies in the provision of a removable cleat which is held in position by the bearing of an annular shoulder of a nut or look nut against the enlarged lower end of the cleat. Further the angle of the annular shoulders 10, 10a of the nuts 8, 8a respectively may be more or less than the angle indicated. As long as the nut has a shoulder which engages the inner or enlarged end of the cleat, and as long as the nut has a threaded or a pin and slot connection with a base member permanently attached to the shoe sole, I

consider such combinations within the obvious scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is t 1. A demountable cleat for an athletic shoe comprising a circular base member having an exteriorly threaded periphery adapted to be secured to a shoe sole, a cleat of conical conformation having an enlarged attachment portion, and a nut having interior threads to engage the threads of the base, with a tapering annular shoulder for frictionally bearing against the enlarged end of said cleat, said cleat and base being provided with means for ensuring their axial align- "ment.

2. A demountable cleat for an athletic shoe comprising a circular base member having an exteriorly threaded periphery adapted to be attached to a shoe sole, a'cleat of conical conformation having an enlarged attachment portion, and a nut having interior threads to engage the threads of the base, with a tapering annular shoulder for frictionally bearing against the enlarged end of said cleat, said cleat and base being provided r be attached to a shoe sole, a cleat of conical conformation having an enlarged attachment portlon, and a nut having interior threads to engage the threads of the base,
